PAINTERS ROOF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 612,256, dated October 11, 1898.

' Application filed April 17, 1897. Serial No. 632,620. (No model.)

T0 00% whom it may concern.-

Be it known that I, MARTIN MATTSON, a citizen of the United States, residing at Sellwood, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Painters" Roof -Brackets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in roof-brackets; and the object of the same is to construct an improved bracket which may be supported upon roofs of various inclinations and adjusted to suit the same, the said bracket being simple in construction and convenient in manipulation.

The invention consists of the novel features of construction hereinafter particularly set forth and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective view of my invention in position upon a roof, and Fig. 2 .is a detached view of one of the supports.

Referring to the drawings, 1 indicates legs, which are adapted to rest upon the roof and provided on their under sides with the tangs or projections 2, which engage the surface of the roof to prevent the slipping of the bracket. The perforated lugs 3 are formed upon the upper ends of these legs, and between these lugs are pivoted the securing bars or straps 4.

The opposite ends of these straps are formed with perforated lugs 5, between which are pivoted the upper ends of the curved supporting-arms 6. These arms are twisted adjacent their upper ends, as at 7, and formed with the loop 8, by means of which they are pivoted to said straps. Raised from the legs 1 are the perforated lugs 9, between which extend the lower ends of the curved arms 6. These arms are provided with a series of perforations 10, by means of which they are adjusted, a bolt 11 passing through the perforated lugs and securing the arms in the proper adjustment. The board 12 connects the two supports, the same being secured to the straps 4 by the bolts 13.

The lower ends of the legs arev formed Y- shaped, as at 14, whereby the structure is made more staple. It will be found convenient to use two brackets, the workmen standing upon one while they are placing the other in proper position. Fonconveniently positioning the brackets I provide the rod 15, provided with the handle 16 on its free end and pivoted to the board 12. When not in use, this rodmay be swung downward to rest upon one of the supports, where it will be out of the way.

When it is desired to adjust the bracket to,

suit the inclination of the roof, the bolts 9 are removed and the curved arm 6 adjusted within the perforated lugs of the legs until the board is moved at the proper inclination. WVhen not in use, the arms may be moved through the perforated lugs until the board is folded flat upon the supporting-legs, when the arms may be secured in position by the bolts. The bracket may thus be conveniently moved from place to place, the same taking up but little space.

From the above description it will be seen that I have produced a very simple and convenient construction of roof-bracket,the same being capable of adjustment to suit inclinations of different roofs.

Having thus described my invention, what Iclaim as new, and desire to secureby Letters Patent, is-

1. A roof-bracket, comprising supportinglegs provided with engaging means and with perforated lugs, a board pivoted to said legs and curved supporting-arms pivoted to the free end of said board, provided with a series of perforations, and adapted to fit between said lugs and be held in place by pins extending through the registering perforations in said lugs and in said arms.

2. A roof-bracket comprising the supporting legs, tangs projecting therefrom and adapted to engage the roof, straps pivoted to the upper ends of the supporting-legs, boards secured to said straps,- curved supportingarms pivoted at their upper ends to the op posite ends of the straps, perforated lugs upon the supporting-legs through which said arms are adapted to extend, the arms being provided with a series of perforations, and securing devices adapted to pass through the perforated lugs and the perforations of the I arms for holding the latter at the proper adj ustment, substantially as described.

3. A roof-bracket comprising supportinglegs substantially Y-shaped at their lower ends, straps pivoted to the upper ends of the legs, a board secured to the straps, curved supporting-arms pivoted at one end to the opposite ends of the straps, perforated lugs raised from the legs adjacent their lower ends, said arms provided with perforations, and se curing means passing through the perforated lugs and perforations of the arms for holding the latter at the proper adjustment, substantially as described.

4. A roof-bracket comprising supportinglegs, straps pivoted thereto, a board secured to said straps, arms pivoted to the straps and adjustable upon the legs, a rod pivoted to the board, a handle formed on said rod by means of which the bracket is moved from place to place, and means for securing the bracket to the roof, substantially as described.

In testimony Whereof I have signed this specification in the presence of two subscribing Witnesses.
